Technical Field

[0001] The utility model belongs to the field of beauty blunt needles, and more specifically, it relates to a disposable beauty blunt needle. Background Technique

[0002] Compared with the sharp needle of the sharp needle, the disposable beauty blunt needle can significantly reduce the pain during needle puncture. The blunt needle reduces the damage to blood vessels and nerves, so it reduces problems such as bleeding and congestion, and is safer and more reliable.

[0003] When the needle seat of the beauty blunt needle is fixedly buckled with the syringe barrel, since the needle seat is relatively smooth and the exposed part between the needle seat and the sheath is small, it is more laborious to assemble on the syringe barrel, and it is difficult to distinguish whether the assembly is secure. Content of the Utility Model

[0004] The purpose of the utility model is to provide a disposable beauty blunt needle to solve the above problems.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Its structure includes a crystal needle seat, a sheath, and a blunt needle tube. The tail of the blunt needle tube is embedded inside the crystal needle seat, and the sheath is sleeved on the outer surface of the crystal needle seat to protect the blunt needle tube.

[0007] The crystal needle seat includes an extension section, an arc-shaped seat, a clamping seat, a needle sleeve, and an arc-shaped head. The extension section is installed between the arc-shaped seat and the arc-shaped head and is an integral structure. The clamping seat is fixed on the outer surface of the needle sleeve. The needle sleeve is connected to the arc-shaped seat. The outer circle of the arc-shaped seat is an arc-shaped structure, which can be better grasped. The clamping seats are provided with four in total and are evenly distributed around the needle sleeve as the center, and are sleeved with the sheath in cooperation. The needle sleeve is internally equipped with a blunt needle tube to play a role of fixing and supporting. The extension section extends the overall length of the connection part, so that the whole can be better grasped and stressed.

[0008] As a further improvement of the utility model, the needle sleeve includes a conical mouth, a fixing hole, and an access port. The access port is connected to the conical mouth. The blunt needle tube is installed inside the fixing hole for fixation. The conical mouth is a conical structure to assist the uniform output of liquid. The conical mouth is connected to the blunt needle tube assembled inside the fixing hole. The diameter of the fixing hole changes from large to small. The largest mouth assists the assembly of the blunt needle tube. The middle section is the longest to fix the blunt needle tube. The smallest mouth limits the maximum movement range of the blunt needle tube and does not affect the output of liquid.

[0009] As a further improvement of the present utility model, the blunt needle tube includes a round head, an outlet hole, scale lines, and a needle tube. The round head and the needle tube are of an integrated structure. The scale lines are located on the outer surface of the needle tube. The outlet hole penetrates through the side surface of the needle tube. Each scale of the scale lines is 10 mm. The round head is located at the front end of the needle tube and is of a closed round head type structure. The outlet hole is opened on the side surface of the needle tube and the surface is smooth. The needle tube remains straight and cannot be bent or deformed. The design of the round head can greatly reduce tissue entanglement and reduce the risk of tissue damage.

[0010] As a further improvement of the present utility model, the sheath includes a shell, a protective head, an inner grid, and a buckle. The inner grid and the shell are of an integrated structure. The buckle is fixed at the bottom position of the inner circle of the shell. The protective head is installed at the upper end inside the shell. The whole shell is in a complete and straight state without defective overflow edges.

[0011] As a further improvement of the present utility model, the buckle is adapted to the card seat and the buckle installation is of appropriate tightness. The protective head increases the stability of the shell and plays a protective role for the internal blunt needle tube inside. The shell itself has a certain hardness and plays a role of supporting and protecting the internal parts. The position where the shell contacts the arc surface seat is arc-shaped, which can make the external force better move the shell.

[0012] As a further improvement of the present utility model, the sheath is in a semi-transparent state and the internal parts are visible. The crystal needle seat has good anti-destruction ability and toughness. The arc surface seat is a smooth arc surface without burrs or rough edges. The design of the extension section and the arc surface seat is more convenient for taking and assembling than the original needle seat.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] First, when the blunt needle tube is inserted into the needle sleeve, the diameter of the fixing hole changes from large to small. The largest opening assists in the assembly of the blunt needle tube. The middle section is the longest to fix the blunt needle tube. The smallest opening limits the maximum movement range of the blunt needle tube and does not affect the output of the liquid, enabling the blunt needle tube to be assembled more stably.

[0015] Second, on the crystal needle seat, an arc-shaped bending structure is designed for the arc surface seat, which can better hold and use the crystal needle seat. The extension section extends the overall distance and increases the holding area, making it more stable. The protruding lines on the outer circle of the arc-shaped head can increase the friction force and better press the buckle with the syringe barrel.

[0016] Third, when the buckle is adapted to the card seat, there is no external gap between the bottom of the shell and the top of the arc surface seat, enabling the blunt needle tube inside the inner grid to be isolated from the outside and play a protective role. The shell itself has a certain hardness to support and protect the internal parts. Moreover, the whole sheath is in a semi-transparent visible state, which can better check whether the internal blunt needle tube is intact. Description of the Drawings

A safe and closed distance is formed between the inside of the housing 21 and the blunt needle cannula 3.

[0031] Among them, the sheath 2 is in a semi-transparent state and the internal parts are visible. The crystal needle seat 1 has good anti-destruction ability and toughness. The arc-shaped seat 12 is a smooth arc surface without burrs or rough edges. The design of the extension section 11 and the arc-shaped seat 12 is more convenient for taking and assembling than the original needle seat. The protruding lines provided on the outer circle of the arc-shaped head 15 can be rubbed for force application.

[0032] Specific usage method and function of this embodiment:

[0033] In this utility model, the blunt needle tube 3 is vertically inserted into the fixing hole 42 through the needle sleeve 14 for support and fixation. The sheath 2 is buckled with the card seat 13 through the buckle 24, so that the bottom of the housing 21 abuts against the top of the arc surface seat 12. The blunt needle tube 3 is placed inside the built-in grid 23 for closed protection. The top of its housing 21 is provided with a protective head 22 to increase the overall stability. The housing 21 itself has a certain hardness and can play a role in supporting and protecting the blunt needle tube 3 inside. When the needle body needs to be used, hold the arc surface seat 12 with an external force. The arc surface seat 12 is an arc-shaped structure, which can be better taken. The drop formed between the extension section 11 and the arc head 15 enables the external force to fix it on the syringe by pressing the arc head 15. Detach the buckle 24 from the card seat 13 to take down the sheath 2. The scale line 33 on the needle tube 34 indicates the moved scale clearly. The round head 31 is a round head structure, which can greatly reduce tissue entanglement and the risk of tissue damage. The liquid is transported into the conical opening 41 through the access port 43. The conical opening 41, through its own conical structure, assists in evenly inputting the liquid into the blunt needle tube 3 and is injected through the outlet hole 32. The outlet hole 32 is designed as a side outlet hole, which helps to improve the injection efficiency and expand the injection range, etc.
